Abstract
Recently, shade matching between the teeth and dental porcelain has been investigated in the field of esthetic dentistry.
This study compared two types of spectrocolorimeters, a precise machine (HITACHI color analyzer 607) and simple machine (Dental color analyzer), for studying the color of Vita dental porcelain.
Our conclusions are as follows:
1. X, Y, Z values of porcelain after baking dentin were larger than those after baking enamel in the case of using color analyzer 607, while X, Y, Z values using Dental color analyzer recorded reverse order.
2. CIE color coordinates of porcelain after baking enamel were approached a neutral point.
3. It was difficult to decide color of C shade in the case of using Dental color analyzer.
4. CIE a*b* color coordinates recorded lower values after baking enamel than after baking dentin.
5. Dental color analyzer has high reliability and usability.
